IMPROVE!) LATHE-FASTENING.

The Schedule referred to in these 'Letters Patent `and making put of th `same.

l I, J AMES G.' STOWE, of the city and county of Providence, and State of Rhode Island, have invented an Improvement in Latlie-Ilastenings, of' which the followingr is a specification.

To `enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation. 2

Figure 1,`of the accompanying drawing, shows a perspectiveview of the` interior of a tail-stock or cricket, with the fasteningtfapparatus represented vtherein; A being the tailstock; B, the bed of the lathe, F', the lathe-shoe or,clamp; a perpendicular rod, secured to Atl1e-eam--blook D at oneend, and passingthrongh `tbe sboe'E, and holding the same by a nut or shoulder at the other, so as to turn vin the.A

shoe; E, a lever, fastenedzto cam-block D 5 and I, one

of`.two cam-surfaces or inc lines, cast with or fastened to the' tal-stoek, and represented by I I in Figure 2, which is another view of the cam-apparatus used.

' v By moving the levers E to the right or left, as desired, it will readily be seen, by the working of the cam-surfaces of D upon those of I I, how the fasten ing and loosening of the stock are e'ected.
